If you look at the link I posted there are literally hundreds of pages of information about the CHF. Everything you need , pics instructions, discussions of the pros and cons are there. What you need for a FR3 are 15mm , 18mm wrenches and a small jack to move the sway bar once it has been loosened. Torque wrench and blue locktite are also helpful.

No offense Barbara, but unless you've got a breaker bar and some decent upper body strength, I think you might find the CHF hard to do. The torque spec is supposed yo be 68 ft lbs? But when the cornfed boy named Jethro in Dearborn put mine on, I think they were torqued to HNNNNGGGHHHHHHH +/- a few foot pounds. It was everything I could do to break mine loose, and I am not lacking for strength or tools.
